Summary:

The Pierce Limestone of the Stones River Group in central Tennessee consists of gray to blue gray, dense, very fined grained, thin bedded limestone. Beds are separated by gray calcareous shale partings. The Pierce contains a diverse fauna of brachiopods and bryozoans. Thickness is 23 to 28 feet. Overlies the Murfreesboro Limestone and underlies the Ridley Limestone, both of the Stones River Group. The Pierce was deposited in a quiet subtidal, normal marine environment.
